Subject: [PATCH v8 0/3] ARM: sun7i/sun6i: irqchip: Irqchip driver for NMI controller
Date: Wed, 26 Mar 2014 22:50:45 +0100 [thread overview]
Message-ID: <1395870648-17240-1-git-send-email-carlo@caione.org> (raw)
Allwinner A20/A31 SoCs have a special interrupt controller for managing NMI.
Three register are present to (un)mask, control and acknowledge NMI.
These two patches add a new irqchip driver in cascade with GIC.
Changes since v1:
- added binding document
Changes since v2:
- fixed trigger type in DTS
- new explanations in binding documentation
- added support for A31 (sun6i)
Changes since v3:
- changed compatibles
Changes since v4:
- fixed binding documentation
Changes since v5:
- switched to handle_fasteoi_irq handler to avoid the double
interrupts issue
Changes since v6:
- changed node name
- deleted defaulted interrupt-parent property
Changes since v7:
- fixed IRQ number in sun6i
- NMI disabled before registering the IRQ handler
